I have an ideea that not only can help whith the BEAST Mark2jetpackrobots, but also make for some pretty cool upgrades and equipment for bosses and enemies.
The armor is a layer of pixels that deflects attacks, but gets destroyed in the prosses. If it's an arrow that hits it, the arrow will go one pixel deep into the armor, and then disapear. If a sword would hit the armour, it also would dig one pixel into the armor, but would then deflect of it.
This could not only make for massive and awesome upgrades and new tiers for the already existing enemy robots, but also make for new bosses and enemies. It could also make for a new branch in the upgrade-tree.
To banance out for the player, it can be accessed late in the upgrade-tree. The armor could also have manny cool designs, and upgrades can make them thicker or lighter.
please come with suggestions or improvements ;)
